2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98

Portable folding seating is well known and outdoor pieces are often referred to as “lawn furniture”. For example, folding chairs have previously been provided which include metal tubing frames that can be folded with respect to each other and with the seat folded therebetween. Such chairs tend to have the advantages of being relatively lightweight, easy to transport and inexpensive. However, a disadvantage relates to their lack of adaptability to sloping and uneven support surfaces. Such surfaces are often encountered outdoors, while fishing or hunting. Many portable chairs with telescopically adjustable legs have been proposed to compensate for such uneven terrain.

Often there is a need to set down equipment or food or other items being carried as well as to sit down outdoors or there may be more than one person, such as at an outdoor event. The prior art does not adequately address these needs one portable seat.

Prior art U.S. Patent Application #20040189062, published Sep. 30, 2004 by Knight, provides an all terrain bench pack which is carried by one person the same way you carry a backpack. The unit has quick release hardware, padded compartments, and indestructible and water proof material and zippers with scent-lock system. The frame converts to a very comfortable and sturdy bench (seat) without disconnecting anything. Each of the four legs adjusts individually to different lengths to assure a comfortable and level seat regardless of terrain. Extra large feet keeps everything stable in uneven rocky or soft ground. The bench (seat) sports a back for extra comfort while sitting long periods.

Prior art U.S. Pat. No. 6,039,403, issued Mar. 21, 2000 to Hargroder, is for a shower/bathtub transfer chair that is capable of disassembly into five basic components. The chair seat and back structures, separable from each other and from the support frame for the device, serve as two of the five components. The remaining three components include an inside leg frame component, an outside leg frame component, and a cross frame component. When disassembled through the use of locking pin mechanisms, each of the five components described provide a generally planar geometry that can be stacked and arranged within a rectangular, suitcase-styled enclosure, for transport and/or storage.

Prior art U.S. Pat. No. 966,891, issued Aug. 9, 1910 to Dudley, claims a laterally extensible seat which may be adjusted to change the seating capacity thereof. The seat comprises a plurality of telescoping parts, which when in collapsed condition constitute a single seat and when extended form an enlarged seat for the accommodation of two or more persons. The seat is portable and the extensible seat, extensible back and leg portions may be folded to be stored in limited space

Prior art U.S. Pat. No. 371,091, issued Oct. 4, 1887 to Miller, describes an extensible seat, such as a church pew, wherein the back portion and bottom seat portion have laterally extendable telescoping end sections. The telescoping sections are formed from slats in the back or seat and the end section which are positioned alternately and relative to each other to allow lateral movement of the end sections. The Miller device is not portable.

Prior art U.S. Pat. No. 5,660,436, issued Aug. 26, 1997 to Wilson, discloses a laterally extendable furniture device that includes a primary support section and a supplemental support section slidably connected to the primary support section for movement between a retracted position and an expanded position. At the retracted position the supplemental support section is stored within the primary support section, and at the expanded position the supplemental support section extends laterally from the primary support section to provide an expanded support surface. The laterally extendable furniture design can readily be adapted to a variety of furniture pieces including chairs, tables, desks and shelves. The furniture device is manufactured from molded plastic components, making it easy and economical to manufacture and durable.

Prior art U.S. Pat. No. 6,135,545, issued Oct. 24, 2000 to Liao, indicates a multifunctional furniture assembly including four furniture units that can be assembled to form a bed, a table, or a chair. First and second furniture units are mounted juxtaposed to other yet allowing sliding movement relative to each other. Third and fourth furniture units are mounted juxtaposed to each other and behind the first and second furniture units, respectively. The third and fourth furniture units are also slidable relative to each other. The third and fourth furniture units may be pivoted relative to the first and second furniture units and then positioned to form a length-adjustable chair.

Prior art U.S. Pat. No. 6,095,607, issued Aug. 1, 2000 to Wenzel, provides a universal adjustable-leg chair having four telescoping legs with provision for setting each leg at a desired length. The chair adjusts to very uneven terrain so that the user can sit in a generally level and comfortable position especially for fishing on the bank of a river or lake, uneven camp sites, graded spectator seating locations, etc. The folding aluminum chair has horizontal connecting braces extending across front and back at the bottom ends of upper leg sections which comprise tubes of the telescoping connection. When the lower extensions of the telescoping legs are fully removed, the chair serves as a beach chair with the connecting braces being the primary contacts with the sand or ground.

Prior art U.S. Pat. No. 6,056,353, issued May 2, 2000 to Meara, claims a lightweight, portable, adjustable folding chair accommodated specifically for persons with a joint disability which causes sitting or rising from a seated position to be difficult including partial or total hip replacement patients. The chair has adjustable height legs, solid cushioned seat and solid arm rests. The feet of the chair are covered with replaceable rubber tips for safety. The chair may be folded for transport and storage. A handle within the backrest is included for ease of carrying.

Prior art U.S. Pat. No. 3,765,718, issued Oct. 16, 1973 to Chen, illustrates a folding chair having four separately adjustable, extendable telescoping legs which are pivotally connected to the bottom of the seat. The legs may be retracted and folded underneath the seat when not in use.

What is needed is a portable knock-down seat which telescopically extends to become a bench or wide seat for use by sportsmen, as a shower chair, as a patient transfer bench, as a seat for one or two at an outdoor event, as a stool, or for other situations requiring a portable expandable bench the portable seat comprises a laterally extendable telescopic bottom, a detachable and laterally extendable telescopic back, two detachable and vertically adjustable telescoping leg assemblies, detachable armrests, and a means for carrying the portable seat.
